In the txt file named "2008-2016.txt" we have the parties that we define as anti-systemic
for the elections of 2008, 2009, 2011, 2014, 2015 and 2016. We define the variable 
"Vote share of anti-systemic parties" asthe ratio of anti-sytemic votes divided by valid 
votes for each group category (CERA and non_CERA) and for every region. The variable 
"Rise of anti-systemic vote" takes the valuof one if the variable "Vote share of anti-systemic parties" 
increases between 2 elections and zero otherwise.For more details on the definition of anti-systemic 
parties see 2 paragraphs before T1. The data "all years_v2.dta" are in staggered format. For the results 
in Columns 1 & 2 in T2 we run fixed effects with year and region dummies and also treatment lags.
